Mass-deployed network device password authentication method and password authentication system

Abstract

The invention provides a password authentication method and password authentication system for network devices which are deployed massively. The system comprises frontend network devices, data access clients, a password management server and a data backup server. The frontend network devices, the data access clients, the password management server and the data backup server are mutually connected through a network. The password management server comprises a first receiving module, an MAC address obtaining module, an MAC address and random number relationship list maintaining module, a random number search module, a management key obtaining module, an access password calculation module and a first sending module. The method and the system have the advantages that the access passwords of all network devices can be periodically and automatically updated, the access password of each network device is ensured to be unique, the access password itself has high anti-break capability, the workload of management and maintenance personnel is reduced, and the use security of the network devices is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of network security, and in particular relates to a password authentication method and a password authentication system for network equipment deployed in large quantities. Background technique [0002] At present, many network devices deployed in large quantities, such as network cameras and various Internet of Things detectors that transmit data through the network, etc., require password verification to access, thereby ensuring the security of network devices. [0003] In the prior art, equipment manufacturers generally set a unified simple access password for network equipment when leaving the factory. Therefore, the user needs to change the access password of the network device during actual use, so as to achieve the effect of ensuring information security. [0004] However, in the process of actual use, because the actual deployment of network devices is very large, if the passwords of the network devi...

Problems solved by technology

[0004] However, in the process of actual use, because the actual deployment of network devices is very large, if the passwords of the network devices are changed one by one, the workload is very huge, and the management and maintenance work is also very cumbersome. Therefore, many users do not have access passwords. To modify, only use the factory password of the network device, or only perform a unified password modification on the network device, and, in order to facilitate the operator's memory, often modify the access passwords of all network devices to the same access password, resulting in a lot of big security risk

In practice, there has been an information leakage problem caused by a camera manufacturer's equipment due to weak passwords, which has caused losses to users and seriously affected the reputation of the equipment manufacturer.
